TECHNICAL FIELD

The present disclosure relates to a customizable surgical bone-cuttingjigsaw puzzle-type guide device, and more particularly, to acustomizable surgical bone-cutting jigsaw puzzle-type guide devicehaving an improved structure for rapidly and precisely cutting a bone ofthe body along a required incision line, coping with the anatomicaldifference between body parts of patients through patient-specificfabrication, and enabling fixation to the inside of the body by its ownstructure without using additional fixtures.

In addition, the present disclosure relates to a customizable surgicalbone-cutting guide-traction-suction device, and more particularly, to acustomizable surgical bone-cutting guide-traction-suction device havingan improved structure for rapidly and precisely cutting a bone of thebody along a required incision line, coping with the anatomicaldifference between body parts of patients through patient-specificfabrication, and preventing visual interference caused by bleeding orcooling water without using an additional device.

BACKGROUND ART (1) Background Art 1

In general, medical procedures for cutting a portion of a bone for thepurpose of treatment are performed by drawing an incision line on aportion to be treated, fixing a guide to a bone to be treated or anadjacent bone at a position corresponding to the incision line usingfasteners such as screws for smooth movements of a cutting blade alongthe incision line, and then performing cutting.

However, this method for medical procedures causes the followingproblems.

In the related art, cutting is performed in a state in which a guide forguiding the movement of a cutting blade is fixed to a portion to be cutby securely attaching the guide to a surrounding bone using fastenerssuch as screws.

Therefore, since work for fixing the guide to the bone is additionallyrequired, it is difficult to rapidly perform cutting and thus to providehigh-quality medical services, and the portion (in particular, a portionwhich is anatomically weak) to which the guide is fixed may be damagedand thus may have to be additionally treated.

In addition, although such guides have to be provided according todifferent anatomical structures of different persons, guides providedaccording to the same standard are used in the related art for cutting,and thus it is difficult to provide patient-specific medical proceduresand thus to rapid and precise medical procedures.

(2) Background Art 2

Furthermore, in general, when it is intended to cut a bone, an incisionline A is drawn on a portion to be cut as shown in FIG. 12A, and then acutter C is inserted to cut the bone along the incision line A as shownin FIG. 12B.

According to this method, however, a clinician has to cut a requiredportion based on his/her skill or experience while checking the incisionline A with the naked eye, and thus, cutting may be performed not alongthe incision line A to cause unexpected damage to an anatomicalstructure. In addition, even when an assistant device is used forcutting, since the assistant device has to be operated in a narrow spacein a narrow field-of-view condition together with a suction device forsuctioning substances such as leaking blood, it is difficult to performcutting. Accordingly, a clinician has to pay significant attention tocutting to handle these problems, and thus the fatigue of the clinicianmay increase.

As shown in the drawings, the customizable surgical bone-cutting jigsawpuzzle-type guide device according to the embodiment of the presentdisclosure is for guiding a cutting operation in which a cutting toolsuch as a cutter is used to, for example, cut the upper jawbone tocorrect twisting or protruding of the upper jawbone. The customizablesurgical bone-cutting jigsaw puzzle-type guide device includes a mainguide portion 10 and connection portions 20.

As shown in FIG. 2, the main guide portion 10 includes: a main contactsurface 12 configured to be brought into contact with a bone; and a mainguide surface 14 forming a curved guide line G along the main contactsurface 12 and configured to guide a cutting blade.

As shown in FIG. 1, the main contact surface 12 is formed such that themain contact surface 12 extends lengthily along required main incisionlines A of a bone to be cut, and the guide line G is provided betweenthe main guide surface 14 and the main contact surface 12 along the sameline as the main incision lines A.

The main guide portion 10 is shaped such that the main guide surface 14may guide the movement of a cutting blade in a state in which the maincontact surface 12 is fixed to the inside of the body, and thus, forexample, a maxillofacial bone may be precisely cut along the mainincision lines A as shown in FIG. 1.

The connection portions 20 extend from the main guide portion 10 and areconfigured to be connected to a side of a bone such that the main guideportion 10 may be supported by the bone as shown in FIG. 3. Theconnection portions 20 may be detachably attached to the side of thebone by their own structure.

The customizable surgical bone-cutting jigsaw puzzle-type guide deviceof the embodiment of the present disclosure provides merits in that acutting portion may be precisely cut while a cutting blade is guided bythe main guide portion 10 along a required incision line, and theconnection portions 20 extending from the main guide portion 10 may beattached to the inside of the body without using additional fixtures forrapid and precise medical procedures and high-quality medical services.

In the current embodiment, the bone to be cut may be the upper jawbone,and the side of the bone to which the connection portions 20 areattached may correspond to a medical guide M coupled to teeth in theoral cavity. Examples of the medical guide M may include a surgicalstent for implantation and a bracket fixed to teeth for upper or lowerjawbone treatment.

As shown in FIG. 3, the connection portions 20 include coupling bosses22 configured to be press fitted into holes of the medical guide M.

In the current embodiment having the above-described configuration, themain guide portion 10 configured to guide the movement of a cuttingblade may be fixed in the oral cavity by its own structure without usingadditional fixtures such that the speed and precision of medicalprocedures may be improved.
